Original application filed June119, 1922Seria1No. 569,346. Divi-ded' and this application filed-June 20,

1923. ',"Serial To all 'fw/wm. t may cof/10mm Beit known Vthat I, MILTON KOHUNV` nection withburners andheaters, thefsame being a division of my application for patent iledJ une `19, 1.922, Serial No. 569,346. One of the objects of thefvinvention-is to provide'a radially armed support or spider which may be rmly. secured uponA burner; Lubes of .varying sizes,` the arms ofthe support :being inclined and provided with'cor-v rugations adapted to center `and maintain various :articles over a gas flame, these armsY terminating in members suited to engager and centrally support an oven or heat ref tamer used in connection.

Another purpose is to produce devices engageable with the support whereby thm heat rising. from a gas flame is disseminated and equalized over a considerable area, enf: closed or otherwise, so as to equally alfect objects lin a uniform manner.

These several aims and others which will appear as the description progresses, are accomplished by the novel construction and arrangement of parts hereafter described and shown in the accompanying drawing, in which Figure l is a plan vView of thespiderlike support in detail.

The spider illustrated will be found of much importance, providing as it does,

means forxsupporting various i articles v and devicesfor deflecting'andV uniformly distributingy the heat las further yon described.

Said spider consists of a central-.ring yor hub/.50, from which extends .radial risers 5l turned outwardly' at a uniformheight, pren sen-ting inclined` arms 52 f having serrations 3B-won#theinnuppem gradually irisingA sur-A faces,z;- thesenarmsfbeing; Aodset downward vto present outwardly bevelled. faces 54 kand terminateaiin zoutstanding support elements Fig. vl() or. an: annular flange :57? as .shown in Fig. 2, v.butzin alle caseswsaid `bars or projections `are,preferablyi. of triangular cross section, presenting wedge-shaped-lovw er edges in vorder lto avoid. interrupting the flow of fuel .gasjthroughjthe tubeon which they restf Various means for. maintaining the spider in :rigid position' relative Eto. the burner tube may be used, in one ofwvhi'ch the hub 50 is extended-downwardly .fto loosely lit over the. top,` ofl the burner tube andv provided withvthumb ...clamp screwsnto impinge. upon the tube:

Work' supports `are-shown. in Figs. `3 to l0, the sanierte be Vusedfe'ither,withsor. without an y ovensor other vform of'j'cover .as def sired.

The device shown inlFigs.. 3 andil consistsriof: a yconcave circularbody 80, yhaving in its lower surface a plurality of circular grooves :8l interrupted `'byt radial c. grooves SQf-tending: to :break the: heat waves impinging upon Ait 'andufnear the edges are pairs of opposed lugs 83 having between them spaces 84T adaptedftoengage on opposite sides of'eac-h.y ofthe arms152 to be centered and held in place thereby.

Extending. rigidly upward fromr near the edge .'.of-the :plate 8() arexposts 815 adjustable asrfto. length'randf whiohficany also be pro-` vided with ball or gimbal joints so that. the upper support or plate can be placed at any desired angle.

The upper ends of the posts 85 arefixed in a flat disc 86, presenting a level upper surface to receivc work parts, this plate being perforated, asy at 87, to freely permit the passage of heat and the. edge at the disc 86 is preferably downturned or beaded as at 88 to prevent the flame from creeping over it.V

In the modification shown inFigs. 5, 6 and 7 the lower surface of the body 80 is. provided with similar grooves and lugs 88 and the spacing posts 85 are fixedin the body 80 to rigidly support the disc 86, which may be identical with that described or corrugated as shown. i

In Fig. 8 the device as shown is composed of, a concave plate 90 formed to produce lugs 9lqengageable with the arms 52, and its edge is turned up tofform a band 92 from which extends prongs 93 adapted to enter appropriate openings yin the disc 94, which is similar in function to the discs already described. f'

- The ,action of this device will bev readily understood and appreciated, as in operation the heat from thev burner impinges and breaks on the bottom plate, which is relatively small in area, and passing itsedge, is transmitted to the top discs or plates from all directions, lheating the work in a uniform and thorough manner.

It is preferred that the material usedin construction of the devices be non-oxidiza ble in character and it will be clear that when used in connection withan oven the not as restrictive 'or limitativeof theinvention, of which obviously an embodiment Amay be constructed including many modifications without departing `from the general scope.

herein indicated and denoted in the appended claims. i

I-Iaving thus described my invention, what I claim as'new and desire to secure vby Letters Patent, is

1-. A work support for gas burners comprising a spider having radiating` arms and a crown ringadapted to engage the top of a burner tube, means on said arms adapted to prevent sliding movement-of an article placed thereon, and means at the ends of said arms for supporting a cover. f

2. A work support for/gas burners com prising a ring suited to engage the end of the burner tube, means forvremovably se 3. -A work support for gas burners ,com-

prising a three armed spider, means on said spider arms for engaging a cover, supporting elements extending transversely across said spider, said elements being of wedgef shaped cross section adapted to seat on the top of the burner tube, and means for rigidly engaging vsaid spider tothe burner-tube 4:. A work support .for gas burners comprising a Vspider having radiating arms, means on said arms adapted toprevent sliding lmovement of an article placed thereon, support' means for vcasings at the ends of said arms, said spider` having a hub at the yinner ends of the arms suited to engage a burner, and means in said hub adapted to engage upon a burner tube.

5. A work support for gas heaters comprising a spider, a removable concave'body having circular and radial grooves in its lower surface, means for attaching said body to said spiderfover a heater, a llevel disc of larger diameterthan said body, and connections between said body and disc whereby. they are held in adjustable spaced relation.

- 6. The vcombination with a gasheater and i an armed spider securedk thereover, of a concave. body having a serrated junder -surface, lugs extending therefrom adapted to engage the arms of said spider, a flat discv of larger area supported at a spaced entranceabove said body, and a bandon said body enclosing the space betweenthe body and disc..

7. The combination with a gas heater and an armed spider secured thereover, of'aremovable deflecting body having aserrated under surface, lugs extendingy therefrom adapted to engage the arms of saidk spider, a disc having an undulating surface of larger area than said body, and yconnections between said disc and body, whereby they are held in spaced relation. o

8.y 'I'he combination with agas heater and an armed spider secured tliereover, of` a separable removable deflectingbody having a serrated under surface, lugs extending therefrom adapted to engage the arms of said spider, and a flat 'disc of larger areav supported in adjustable spaced relation to said body. i

In testimony whereof I have signed my name to this application.
